DYAS SHELTON, OF SANTA ROSA, CALIFORNIA.

VEHICLE- BOLSTER.

SPECIFICATION forming part of Letters Patent No. 255,736, dated March 28, 1882,

Application filed January 3, 1882. (No model.)

To all whom it may concern:

Be it known that I, DYAS SHELTON, a citizen of the United States, residing at Santa'ltosa, in the county of Sonoma and State of Calitbrnia,haveinvented certain new and useful Improvements in Vehicle Bolsters and Plate in Conjunction with a Sand-Board; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to wagon bolsters and A plate, in conjunction with a sand-board so a1;-

ranged that the strain and wear heretofore brought to bear upon the king-bolt and plates by the lateral motion of the vehicle are thrown in part upon and sustainedby said bolster, plates, and sandboard.

The ordinary plates with which 1 am familiar .are so arranged that the rocking bolster by its lateral motion and extended play causes said plates to wear at their ends. This is particnlarly the case in driving a loaded wagon has sufficient play to out the sand-board, and

sometimes they look. I overcome these difficulties by the mechanism illustrated in the accompanying drawings, in which Figure fl is a front elevation, showing my improvement attached to a sand-board and partially secured thereto by means of a kin gbolt. I Fig. 2 is a perspective view of the sandboard plate. Fig. 3is a front elevation of the 5 bolster, plate, and king-bolt.

The letter A represents the arms of the bolster; A, the front of the elliptical shank, formed of and constituting a part of the bolster. Bistheelliptical metallic plate,screwed or otherwise attached to the bottom of the shank A. O is the saint-board plate, having lugs E E. D is the sand-board. F is the king-bolt. G represents the circular slot in the sand-board to receive the king-bolt. The letters f f indicate the screws, tending to secure the sand-board plate 0 to the sand-board D. m m are the slots in the sand-board to receive the screwsff orother connectingmeans.

In the drawings it will be seen that thelugs E E of the sandboard lap over two sides of the plate B, by means of which (assisted by the king-bolt) said plate is held firmlyin the recess in the sand-board plate. The bolster A, being secured to the plate B, is also necessarily 6 held. The bolster A and plate B turn freely in the recess in the sand-board plate 0. The lugs E E are of sufficient width to keep the plate B from escaping.

Having thus described my invention, I claim. 0 as new and de'sireto secure by Letters Patent In a vehicle, the sand-board 1), having plate 0 connected thereto by means of screws ff, said plate having lugs E E, in combination with elliptical plate B, which is attached to elliptical shank of bolster A, said bolster'having tapering arms A A, the whole being sooured by the king-bolt F, in the manner and for the purposes set forth.

In testimony whereof laffix my signature in presence of two witnesses.

DYAS SHELTON.
